Abstract

In spinning a conjugate filament, the orifice is in the form of a slot (20), and an interface (26) between two conjugated polymers flowing through the orifice extends transversely across the slot in at least two locations. The spun stream thus comprises a plurality of separate spun interfaces. Preferably the slot meanders back and forth across the interface (26). The spun stream is solidified, and may thereafter be separated into sub-filaments. The two polymers are for example nylon 66 and polyethylene terephthalate.
